System and Method for Determining Line of Sight (LOS)

A method performed by a first device, the method comprising:

• communicating, by the first device, with a second device, a line of sight (LOS) determination request including a dual polarization procedure indicator indicating a dual polarization procedure is used in LOS characterization of a transmission between the first device and the second device;
• transmitting, by the first device, a first signal on a first resource of a channel;
• and
• transmitting, by the first device, a second signal on a second resource of the channel, with the first and second signals comprising a single bit sequence with orthogonal polarization and are multiplexed in a frequency domain or a code domain.

A first device comprising:

• a non-transitory memory storage comprising instructions;
• and
• one or more processors in communication with the memory storage, the one or more processors execute the instructions to:
• communicate, with a second device, a line of sight (LOS) determination request including a dual polarization procedure indicator indicating a dual polarization procedure is used in LOS characterization of a transmission between the first device and the second device,
• measure a first signal on a first resource of a channel, and
• measure a second signal on a second resource of the channel, with the first and second signals comprising a single bit sequence with orthogonal polarizations and are multiplexed in a frequency domain or a code domain.
